Abstract (en)
[origin: EP4104998A1] Provided is a thermoplastic resin composition exhibiting both high transmittance and low haze and having excellent transparency and excellent scratch resistance and toughness. The thermoplastic resin composition of the present disclosure contains 50 % to 99 % by mass of methacrylic resin (A) and 1 % to 50 % by mass of thermoplastic polyurethane (B), wherein the methacrylic resin (A) contains 80.0 % to 99.9 % by mass of methacrylate ester monomer unit, 0.1 % to 20.0 % by mass of vinyl monomer unit containing a vinyl monomer copolymerizable with a methacrylate ester monomer excluding maleic acid and maleic anhydride, and 0 % to 4.0 % by mass of maleic acid and/or maleic anhydride monomer unit, and the thermoplastic polyurethane (B) has a structural unit derived from polyester polyol and a structural unit derived from isocyanate having an alicyclic ring.
